suggestion as addon for opera mail

I really like the light mail client Opera Mail, however for a fee I would not mind having the option to include one or more e-mails in an new e-mail I am composing. This option is there in Outlook yet it is not present in Opera Mail nor the Opera Browsers mail functionality.

I simple way to migrate e-mail from one install on one PC to another would be another on my personal wishlist.

Again if Opera would charge a fee for this I would not mind paying. See the way Premium Soft of Navicat fame solves this with some minor purchasing options, an Essentials variant and a more De Luxe or perhaps Opera could call it the Professional variant which could include an option to request an read e-mail request and a option to encrypt your email with PGP.
